Abstract: Solid-liquid equilibrium data for three binary systems: 4-hydroxybenzaldehyde/3-bromo-4- hydroxybenzaldehyde,4-hydroxybenzaldehyde/3,5-dibromo-4-hydroxybenzaldehyde,3-bromo-4-hydroxy-benzaldehyde/3,5-dibromo-4-hydroxybenzaldehyde were determined by differential scanning calorimetry and corresponding phase diagrams were given.λh equation and Wilson equation were used to correlate the data. It was shown that the results obtained by two models were both satisfactory.
